This paper provides guidelines for calculating the EDGE index at the national level to monitor extinction risks of evolutionarily distinct species and highlights trends in threatened species.

This paper develops efficient date interpolation algorithms to fully date a large phylogenetic tree, enabling robust estimates of phylogenetic diversity across 2.3 million species.

This study identifies priority crayfish species for conservation based on phylogenetic diversity and climate change vulnerability, finding that protecting these species could safeguard significant evolutionary history.

The paper examines how interactions between six anthropogenic threats affect functional and phylogenetic diversity in Testudines and Crocodilia, finding synergistic effects when diseases or invasive species interact with other threats.

The paper assesses angiosperm evolutionary history at risk of extinction and identifies conservation priorities using phylogenetic trees and extinction risk estimates.

This paper introduces a metric called FIRE to prioritize conservation of functionally irreplaceable species at risk of extinction by integrating trait data and extinction risk.

This paper calculates continuous extinction risk from historical IUCN Red List data, revealing that species attributes like taxonomy, body size, and habitat specialism influence risk beyond the current categorical assessments.
